Class wrapping convolution of two functions.

Class wrapping convolution of two functions: evaluation of \(\int f(x)g(x-t)dx\)

The convolution is performed by default using FFTW if it is available . One can pass optionally the range of the convolution (by default the first function range is used). Note that when using Discrete Fourier Transform (as FFTW), it is a circular transform, so the functions should be approximately zero at the end of the range. If they are significantly different than zero on one side (e.g. the left side) a spill over will occur on the other side (e.g right side). If no function range is given by default the function1 range + 10% is used One should use also a not too small number of points for the DFT (a minimum of 1000). By default 10000 points are used.
